Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a request to apply demodulation reference signal (DMRS) bundling to uplink transmissions. The UE may transmit multiple uplink transmissions. The UE may transmit an indication of whether the UE is able to comply with the request based at least in part on whether the UE is able to maintain phase coherence across the multiple uplink transmissions. Numerous other aspects are provided.
Claims30
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit a capability report indicating that the UE is capable of uplink demodulation reference signal (DMRS) bundling;
- receive a request to apply DMRS bundling to uplink transmissions;
- transmit multiple uplink transmissions;
- and
- transmit, for each of the multiple uplink transmissions an indication, in an uplink control information (UCI) or a particular DMRS sequence, based at least in part on the request, of whether the UE applies DMRS bundling to the each of the multiple uplink transmissions, based at least in part on whether the UE is able to maintain phase coherence across the multiple uplink transmissions.
A network entity for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive a capability report indicating that a user equipment (UE) is capable of uplink demodulation reference signal (DMRS) bundling;
- transmit, to the UE, a request to apply DMRS bundling to uplink transmissions;
- receive multiple uplink transmissions;
- and
- receive, for each of the multiple uplink transmissions, in an uplink control information (UCI) or a particular DMRS sequence, an indication of whether the UE applies DMRS bundling to the each of the multiple uplink transmissions.
